CDK-inhibitory 2-heteroaryl-pyrimidines, their production and use as pharmaceutical agents

ABSTRACT

This invention relates to 2-heteroaryl-pyrimidine derivatives of general formula I as inhibitors of the cyclin-dependent kinases, their production as well as their use as medications for treating various diseases.

[0001] This invention relates to 2-heteroaryl-pyrimidine derivatives, their production as well as their use as medications for treating various diseases.

[0002] The CDKs (cyclin-dependent kinase) is an enzyme family that plays an important role in the regulation of the cell cycle and thus is an especially advantageous target for the development of small inhibitory molecules. Selective inhibitors of the CDKs can be used for treatment of cancer or other diseases that cause disruptions of cell proliferation.

[0003] Pyrimidines and analogs are already described as active ingredients, such as, for example, the 2-anilino-pyrimidines as fungicides (DE 4029650) or substituted pyrimidine derivatives for treating neurological or neurodegenerative diseases (WO 99/19305). As CDK-inhibitors, the most varied pyrimidine derivatives are described, for example bis(anilino)-pyrimidine derivatives (WO 00/12486), 2-amino-4-substituted pyrimidines (WO 01/14375), purines (WO 99/02162), 5-cyano-pyrimidines (WO 02/04429), anilinopyrimidines (WO 00/12486) and 2-hydroxy-3-N,N-dimethylaminopropoxy-pyrimidines (WO 00/39101).

[0004] The object of this invention is to provide compounds that have better properties than the inhibitors that are already known. The substances that are described here are more effective, since they already inhibit in the nanomolar range and can be distinguished from other already known CDK-inhibitors such as, e.g., olomoucine and roscovitine.

[0099] The compounds according to the invention essentially inhibit cyclin-dependent kinases, upon which is based their action, for example, against cancer, such as solid tumors and leukemia; auto-immune diseases, such as psoriasis, alopecia, and multiple sclerosis, chemotherapy-induced alopecia and mucositis; cardiovascular diseases, such as stenoses, arterioscleroses and restenoses; infectious diseases, such as, e.g., by unicellular parasites, such as trypanosoma, toxoplasma or plasmodium, or produced by fungi; nephrological diseases, such as, e.g., glomerulonephritis, chronic neurodegenerative diseases, such as Huntington's disease, amyotropic lateral sclerosis, Parkinson's disease, AIDS, dementia and Alzheimer's disease; acute neurodegenerative diseases, such as ischemias of the brain and neurotraumas; viral infections, such as, e.g., cytomegalic infections, herpes, hepatitis B and C, and HIV diseases.

[0100] The eukaryotic cell division cycle ensures the duplication of the genome and its distribution to the daughter cells by passing through a coordinated and regulated sequence of events. The cell cycle is divided into four successive phases: the G1 phase represents the time before the DNA replication, in which the cell grows and is sensitive to external stimuli. In the S phase, the cell replicates its DNA, and in the G2 phase, preparations are made for entry into mitosis. In mitosis (M phase), the replicated DNA separates, and cell division is completed.

[0101] The cyclin-dependent kinases (CDKs), a family of serine/threonine kinases, whose members require the binding of a cyclin (Cyc) as a regulatory subunit in order for them to activate, drive the cell through the cell cycle. Different CDK/Cyc pairs are active in the various phases of the cell cycle. CDK/Cyc pairs that are important to the basic function of the cell cycle are, for example, CDK4(6)/CycD, CDK2/CycE, CDK2/CycA, CDK1/CycA and CDK1/CycB. Some members of the CDK enzyme family have a regulatory function by influencing the activity of the above-mentioned cell cycle CDKs, while no specific function could be associated with other members of the CDK enzyme family. One of the latter, CDK5, is distinguished in that it has an atypical regulatory subunit (p35) that deviates from the cyclins, and its activity is highest in the brain.

[0102] The entry into the cell cycle and the passage through the “restriction points,” which marks the independence of a cell from further growth signals for the completion of the cell division that has begun, are controlled by the activity of the CDK4(6)/CycD and CDK2/CycE complexes. The essential substrate of these CDK complexes is the retinoblastoma protein (Rb), the product of the retinoblastoma tumor suppressor gene. Rb is a transcriptional co-repressor protein. In addition to other, still largely little understood mechanisms, Rb binds and inactivates transcription factors of the E2F type and forms transcriptional repressor complexes with histone-deacetylases (HDAC) (Zhang, H. S. et al. (2000). Exit from G1 and S Phase of the Cell Cycle is Regulated by Repressor Complexes Containing HDAC-Rb-hSWI/SNF and Rb-hSWI/SNF. Cell 101, 79-89). By the phosphorylation of Rb by CDKs, bonded E2F transcription factors are released and result in transcriptional activation of genes, whose products are required for the DNA synthesis and the progression through the S-phase. In addition, the Rb-phosphorylation brings about the breakdown of the Rb-HDAC complexes, by which additional genes are activated. The phosphorylation of Rb by CDKs is to be treated as equivalent to exceeding the “restriction points.” For the progression through the S-phase and its completion, the activity of the CDK2/CycE and CDK2/CycA complexes is necessary, e.g., the activity of the transcription factors of the E2F type is turned off by means of phosphorylation by CDK2/CycA as soon as the cells are entered into the S-phase. After replication of DNA is complete, the CDK1 in the complex with CycA or CycB controls the entry into and the passage through phases G2 and M (FIG. 1).

[0103] According to the extraordinary importance of the cell-division cycle, the passage through the cycle is strictly regulated and controlled. The enzymes that are necessary for the progression through the cycle must be activated at the correct time and are also turned off again as soon as the corresponding phase is passed. Corresponding control points (“checkpoints”) stop the progression through the cell cycle if DNA damage is detected, or the DNA replication or the creation of the spindle device is not yet completed.

[0104] The activity of the CDKs is controlled directly by various mechanisms, such as synthesis and degradation of cyclins, complexing of the CDKs with the corresponding cyclins, phosphorylation and dephosphorylation of regulatory threonine and tyrosine radicals, and the binding of natural inhibitory proteins. While the amount of protein of the CDKs in a proliferating cell is relatively constant, the amount of the individual cyclins oscillates with the passage through the cycle. Thus, for example, the expression of CycD during the early G1 phase is stimulated by growth factors, and the expression of CycE is induced after the “restriction points” are exceeded by the activation of the transcription factors of the E2F type. The cyclins themselves are degraded by the ubiquitin-mediated proteolysis. Activating and inactivating phosphorylations regulate the activities of the CDKs, for example phosphorylate CDK-activating kinases (CAKs) Thr160/161 of the CDK1, while, by contrast, the families of Wee1/Myt1 inactivate kinases CDK1 by phosphorylation of Thr14 and Tyr15. These inactivating phosphorylations can be destroyed in turn by cdc25 phosphatases. The regulation of the activity of the CDK/Cyc complexes by two families of natural CDK inhibitor proteins (CKIs), the protein products of the p21 gene family (p21, p27, p57) and the p16 gene family (p15, p16, p18, p19) is very significant. Members of the p21 family bind to cyclin complexes of CDKs 1,2,4,6, but inhibit only the complexes that contain CDK1 or CDK2. Members of the p16 family are specific inhibitors of the CDK4 and CDK6 complexes.

[0105] The plane of control point regulation lies above this complex direct regulation of the activity of the CDKs. Control points allow the cell to track the orderly sequence of the individual phases during the cell cycle. The most important control points lie at the transition from G1 to S and from G2 to M. The G1 control point ensures that the cell does not initiate any DNA synthesis unless it has proper nutrition, interacts correctly with other cells or the substrate, and its DNA is intact. The G2/M control point ensures the complete replication of DNA and the creation of the mitotic spindle before the cell enters into mitosis. The G1 control point is activated by the gene product of the p53 tumor suppressor gene. p53 is activated after detection of changes in metabolism or the genomic integrity of the cell and can trigger either a stopping of the cell cycle progression or apoptosis. In this case, the transcriptional activation of the expression of the CDK inhibitor protein p21 by p53 plays a decisive role. A second branch of the G1 control point comprises the activation of the ATM and Chk1 kinases after DNA damage by UV light or ionizing radiation and finally the phosphorylation and the subsequent proteolytic degradation of the cdc25A phosphatase (Mailand, N. et al. (2000). Rapid Destruction of Human cdc25A in Response to DNA Damage. Science 288, 1425-1429). A shutdown of the cell cycle results from this, since the inhibitory phosphorylation of the CDKs is not removed. After the G2/M control point is activated by damage of the DNA, both mechanisms are involved in a similar way in stopping the progression through the cell cycle.

[0106] The loss of the regulation of the cell cycle and the loss of function of the control points are characteristics of tumor cells. The CDK-Rb signal path is affected by mutations in over 90% of human tumor cells. These mutations, which finally result in inactivating phosphorylation of the RB, include the over-expression of D- and E-cyclins by gene amplification or chromosomal translocations, inactivating mutations or deletions of CDK inhibitors of the p16 type, as well as increased (p27) or reduced (CycD) protein degradation. The second group of genes, which are affected by mutations in tumor cells, codes for components of the control points. Thus p53, which is essential for the G1 and G2/M control points, is the most frequently mutated gene in human tumors (about 50%). In tumor cells that express p53 without mutation, it is often inactivated because of a greatly increased protein degradation. In a similar way, the genes of other proteins that are necessary for the function of the control points are affected by mutations, for example ATM (inactivating mutations) or cdc25 phosphatases (over-expression).

[0107] Convincing experimental data indicate that CDK2/Cyc complexes occupy a decisive position during the cell cycle progression: (1) Both dominant-negative forms of CDK2, such as the transcriptional repression of the CDK2 expression by anti-sense oligonucleotides, produce a stopping of the cell cycle progression. (2) The inactivation of the CycA gene in mice is lethal. (3) The disruption of the function of the CDK2/CycA complex in cells by means of cell-permeable peptides resulted in tumor cell-selective apoptosis (Chen, Y. N. P. et al. (1999). Selective Killing of Transformed Cells by Cyclin/Cyclin-Dependent Kinase 2 Antagonists. Proc. Natl. Acad. Sci. USA 96, 4325-4329).

[0108] Changes of the cell cycle control play a role not only in carcinoses. The cell cycle is activated by a number of viruses, both by transforming viruses as well as by non-transforming viruses, to make possible the replication of viruses in the host cell. The false entry into the cell cycle of normally post-mitotic cells is associated with various neurodegenerative diseases. The mechanisms of the cell cycle regulation, their changes in diseases and a number of approaches to develop inhibitors of the cell cycle progression and especially the CDKs were already described in a detailed summary in several publications (Sielecki, T. M. et al. (2000). Cyclin-Dependent Kinase Inhibitors: Useful Targets in Cell Cycle Regulation. J. Med. Chem. 43, 1-18; Fry, D. W. & Garrett, M. D. (2000).

[0232] Sample Application 1

[0233] CDK2/CycE Kinase Assay

[0234] Recombinant CDK2- and CycE-GST-fusion proteins, purified from baculovirus-infected insect cells (Sf9), were obtained by Dr. Dieter Marmé, Klinik für Tumorbiologie [Clinic for Tumor Biology], Freiburg. Histone IIIS, which was used as a kinase substrate, was purchased by the Sigma Company.

[0235] CDK2/CycE (50 ng/measuring point) was incubated for 15 minutes at 22° C. in the presence of various concentrations of test substances (0 μm, as well as within the range of 0.01-100 μm) in assay buffer [50 mmol of tris/HCl pH 8.0, 10 mmol of MgCl₂, 0.1 mmol of Na ortho-vanadate, 1.0 mmol of dithiothreitol, 0.5 μm of adenosine triphosphate (ATP), 10 μg/measuring point of histone IIIS, 0.2 μCi/measuring point of ³³P-gamma ATP, 0.05% NP40, 12.5% dimethyl sulfoxide]. The reaction was stopped by adding EDTA solution (250 mmol, pH 8.0, 14 μl/measuring point).

[0236] From each reaction batch, 10 μl was applied to P30 filter strips (Wallac Company), and non-incorporated ³³P-ATP was removed by subjecting the filter strips to three washing cycles for 10 minutes each in 0.5% phosphoric acid. After the filter strips were dried for one hour at 70° C., the filter strips were covered with scintillator strips (MeltiLex™ A, Wallac Company) and baked for one hour at 90° C. The amount of incorporated ³³P (substrate phosphorylation) was determined by scintillation measurement in a gamma-radiation measuring device (Wallac).

[0237] Sample Application 2

[0238] Proliferation Assay

[0239] Cultivated human tumor cells (as indicated) were flattened out at a density of 5000 cells/measuring point in a 96-well multititer plate in 200 μl of the corresponding growth medium. After 24 hours, the cells of one plate (zero-point plate) were colored with crystal violet (see below), while the medium of the other plates was replaced by fresh culture medium (200 μl), to which the test substances were added in various concentrations (0 μm, as well as in the range of 0.01-30 μm; the final concentration of the solvent dimethyl sulfoxide was 0.5%). The cells were incubated for 4 days in the presence of test substances. The cell proliferation was determined by coloring the cells with crystal violet: the cells were fixed by adding 20 μl/measuring point of a 11% glutaric aldehyde solution for 15 minutes at room temperature. After three washing cycles of the fixed cells with water, the plates were dried at room temperature. The cells were colored by adding 100 μl/measuring point of a 0.1% crystal violet solution (pH was set at 3 by adding acetic acid). After three washing cycles of the colored cells with water, the plates were dried at room temperature. The dye was dissolved by adding 100 μl/measuring point of a 10% acetic acid solution. The extinction was determined by photometry at a wavelength of 595 nm. The change of cell growth, in percent, was calculated by standardization of the measured values to the extinction values of the zero-point plate (=0%) and the extinction of the untreated (0 μm) cells (=100%).
